Well, for me... I get better reception on my type 57 PVR150's than I do 
on my tv set also. (I'm sure you knew the 500 is just 2 150's) With my 
Sony Wega tv I get pretty good image on almost all chanels but the 
PVR150's actually seem to boost and clean the image quite noticeably. On 
the other hand my type 47 350 is a bit worse than the tv set. I guess 
you'll never really know until you try it at your jack but hopefully 
you'll see the same results as I did. I havn't tried to refine the 
tuning past what my locations lineup is slated for but I wonder if I can 
get some of the snow out of the 350 that way.

As far as building the drivers for debian. One thing to watch out for is 
where it throws the kernel modules. I guess you could edit some things 
to make it put them in the right location but my usual lazy route goes 
something like this if your using a stock gcc-3.3 kernel under sid like 
2.6.11 with standard gcc-4.0 installed.. (lucky for you, I already have 
this written down for my brother who is installing a 500 on sid this 

cd /usr/local/src
wget http://easynews.dl.sourceforge.net/sourceforge/ivtv/ivtv-0.2.0-rc3j.tgz
tar xvfz ivtv-0.3.7c.tgz
cd /usr/local/src/ivtv-0.3.7c/driver/
make CC=gcc-3.3
rm /lib/modules/2.6.11-1-k7/kernel/drivers/media/video/msp3400.ko
make install CC=gcc-3.3
cp *.ko /lib/modules/2.6.11-1-k7/build/drivers/media/video/
cp *.ko /lib/modules/2.6.11-1-k7/kernel/drivers/media/video/

vi /etc/modutils/ivtv

# you'll need something like this for PAL... but double check ivtv_std 
just in case, I use ntsc which is default. Double check your tuner too.
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
options ivtv ivtv_std=2,2 tuner=57,57 tda9887=0,0 ivtv_debug=1,1
options cx25840 no_black_magic=1 i2c_enable=1,1
options msp3400 once=1 simple=1

Then to load the modules I do add something like this /etc/modules

You will probably get away with just 'ivtv' since you don't have to deal 
with saa7127 from the 250's/350's thinking it can take control of your 
150's like me.


install the firmware in /lib/modules as described here
(I use the supported encoder firmware and the audio firmware from the 
cd... When I use just any firmware my stuff doesn't seem to have as good 
quality or as good stability... thats why I use the recommended firmware)

reboot or modprobe the modules

and try it out
cat /dev/video0 > test.mpg
cat /dev/video1 > test.mpg

then you can install ptune to change the channels and do all the mythtv
